Do not assume that a 6” lift kit will require a 6” lift spacer. On many lift kits, the lift for the front end is higher than for the rear. In this case, the lift might be labeled as a 6”, but the rear lift may only be 4”. Contact the lift kit manufacturer for the height increase of the rear. Choose the spacer that is closest to the increased amount of the lift for the rear of the truck. It is preferred to mount the air spring taller — or slightly stretched — than shorter — or slightly compressed. Air Lift company recommends to read installation manuals for the lift kit and the load assist kit to fully understand the interfaces between the two products prior to purchasing.

A second method for determining which lift spacer is needed is to measure between the mounting surfaces of the upper and lower brackets (Fig. 1), then subtract the height of the air spring at design height (Table 1). Choose the lift spacer kit with the appropriate height and angle (Table 2). Take all measurements at curb height (flat surface, no load).
